Son, specially high-speed synchronous main and backup generator rotor.
Background technique
The main and auxiliary synchronization main and backup generator for sending out integrated has been applied on Diesel Locomotives Made in China, but by vehicle
And internal-combustion engine rotational speed limitation, current synchronization main and backup generator revolving speed are confined to 1000r/min.External diesel locomotive user is continuous
Increase, but because external multiple areas or country use narrow gauge railway, the revolving speed of its corresponding internal combustion engine need to reach 1800r/min,
Existing synchronous main and backup generator with the defect in flowering structure due to being not suitable for being dragged by high-speed internal combustion engine:
1. main hair rotor-exciting lead passes through auxiliary hair magnetic yoke structure using cable, auxiliary hair magnetic yoke (mating surface with shaft) is needed
It slots, reduces the matching area of auxiliary hair magnetic yoke and shaft.
2. excitation lead uses the construction of cable, cable tail head and rotor magnetic pole wire connections position, slip ring connecting portion
It should not fix；Cable makes phase mutual friction cable and shaft, auxiliary hair magnetic yoke across auxiliary hair magnetic yoke, is easy to lead at high speeds
Cable failure or connection is caused to loosen and influence motor safe and stable operation.
It is bound on wiring card and shaft 3. main hair rotor-exciting leader cable is fixed using binding strap, to guarantee to tie up
Band tension uniform needs to be equipped with dedicated binding machine and is bound, and increases equipment cost and process costs.
In addition, the rotor of existing synchronous main and backup generator needs the dedicated cooling fan pair of system configuration without fan
Motor carries out cooling channel and needs periodically to influence locomotive space utilization rate, and electrical system is many and diverse to blower cooling system
System is safeguarded.
Summary of the invention
The present invention solves the synchronization main and backup generator on existing diesel locomotive since fault of construction is not suitable for high-speed rotation
Problem provides a kind of high-speed synchronous main and backup generator rotor.
The present invention is achieved by the following technical scheme: high-speed synchronous main and backup generator rotor, including shaft, it is coaxial to pacify
Loaded on the main hair rotor and auxiliary hair rotor in shaft, and be set in shaft and be located at auxiliary hair rotor with the non-phase of main hair rotor
The slip ring of adjacent side；It is axially provided with round unthreaded hole in auxiliary hair rotor rim, the copper screw bolt of TBE (threaded both ends), copper screw bolt are installed in unthreaded hole
Both ends are locked in auxiliary hair rotor rim using copper nut respectively, and the winding excitation lead of main hair rotor is connected through copper screw bolt
To the slip ring of auxiliary hair rotor side, the winding excitation lead of auxiliary hair rotor is directly connected to slip ring.Setting copper screw bolt avoids
The cooperation tightness of mating surface is drilled and influenced on the contact surface of auxiliary hair rotor rim and shaft, and then avoids auxiliary hair magnetic yoke and turns
The problem of axial plane is because that must increase the diameter of axle and auxiliary hair magnetic yoke volume caused by cooperation deficiency.
Further, the winding excitation lead of the winding excitation lead of main hair rotor and auxiliary hair rotor all uses copper strap wire to roll over
The structure of roll forming covers intrinsic first fixed ring in the shaft between main hair rotor and auxiliary hair rotor, auxiliary hair rotor and slip ring it
Between shaft on cover intrinsic second fixed ring, the first winding excitation of the main hair rotor between main hair rotor and copper screw bolt one end is drawn
Line is fixed in the first fixed ring with cable guide, and the second winding excitation of the main hair rotor between the copper screw bolt other end and slip ring is drawn
The winding excitation lead of line and auxiliary hair rotor is fixed in the second fixed ring with cable guide.Reliable fixed form ensures motor
Prevent each lead from loosening, fall off, being broken when running at high speed.Convenient and fast mounting means (does not need to bind using binding strap
Rotor must be subjected to process on binding machine) processing step can be simplified, reduce investment, the maintenance cost of equipment.
Further, increase seam allowance at one in main hair rotor rim left end to be used to that fan, fan and main hair rotor magnetic to be installed
Fan is fastened using bolt using transition fit between yoke and in the end face circumference of main hair rotor rim.
The present invention increases fan on rotor, and the forced ventilation mode of motor is designed as self-ventilation mode, improves locomotive
Space utilization rate simplifies the cooling-fan installation of locomotive.It is connected between main hair rotor-exciting lead and slip ring using copper screw bolt,
Avoid the cooperation tightness for drilling and influencing mating surface on the contact surface of auxiliary hair rotor rim and shaft.Main and auxiliary hair rotor-exciting
Lead is installed additional cable guide using copper strap wire bending and molding and before each connector rather than uses binding strap anchor leg, and work is improved
Skill, it is ensured that type rotor safe and stable operation when running at high speed.The excitation lead and copper screw bolt of bending and molding point
It carry out not insulation processing raising electric property.
